IMPROVEMENT m CAR-HEATERS.

Specification forming part of Letters Patent No. 194,331, dated ,August21, 1877; application filed January 25, 1877.

To all whom it may concern;

Be it known that I, DE WITT O. CHIPMAN, of Richmond, Wayne county, Stateof Indiana, have invented a new and Improved Safety Heating Apparatusfor Railway-Oars or other movable vehicles.

Said invention and improvement consists of reservoirs of water arrangedaround the i1 e in such a manner that water is discharged into theinterior and onto the exterior of the heater in all cases of accident orcollision.

The heater is completely surrounded by a jacket, which would ordinarilybe a suflicient safeguard without the water, but both combined arebelieved to be a perfect protection against fire.

The heating apparatus may be any kind of heater now or that may behereafter used, and it may be located in one or all coaches, or in thebaggage-car.

I do hereby declare that the following is a full, clear, and exactdescription thereof, which will enable skilled artisans make and use thesame, reference being had to the accompanying drawings, and to theletters of reference marked thereon, making part of this specification.

Figure 1 is a perspective, and Fig. 2 a view partly in vertical section,of the same.

A, in Fig. 1, isa funnel to introduce water into reservoir B, and B is areservoir of water entirely surrounding the heater and hiding it Iromsight, as described hereinafter. H is a stove-pipe. J is a cold-air pipefor introducing air into a warm-air chamber, I, hereinafter described.

The pipe J may be located at the top, sides, bottom, or other place, andthere may be as many pipes as are necessary to furnish cold air for theheater. It may be located at any convenient place on the car, or may beextended in front of the engine. The cold air may be forced into J anddriven through the warm-air chamber by the momentum of the train, byfan-blower or other proper power, by pulley over the axle, or steam.

G is a stove of any construction, but is shown herein round and plain,and is used to warm the air for passenger-coaches.

K is a jacket, (seen in Fig 2,) which completely surrounds the reservoirB, the Warmair chamber I, and the heater G.

This jacket K may be made of any suitable metal, but boiler-iron ispreferred for the outside, and a less tenacious metal for the inner. Incase of collision boiler-iron would twist, but not break readily, thusholding the heater iucased and harmless.

The door of the heater is seen at M, Fig. 1, and the orifice shows howwater is putin bya funnel.

The draft of air for the heater, when the door is closed, is obtainedfrom pipe J. When the door is closed and fastened all the interior partsof the heater are shut from sight.

E is a reservoir of water under the heater, having no cover, butinclosed in jacket K, and is used to deluge the heater on the outsidewhen the car is overturned partially or wholly.

L is a pipe to conduct warm air into the coach or through the train, andmayv be prolonged into and through as many cars as desired. It isprovided with large stove would warm an entire train, thus dispensingwith other stoves and fuel, and greatly diminishing the danger of fire,and increasing the carrying capacity of the train.

In Fig. 2, the parts lettered A, H, J, K, G, E, and L, perform the samefunctions as described in Fig. 1, but the invention is better seen inFig. 2, as it presents the interior of the device or improvement to theeye.

is a reservoir of water inclosed in jacket K, which surrounds warm-airchamber I and heater G.

Water is introduced into B through funnel A. B is filled with waternearly up to pipes O 0. When the heater is tilted up partially andwholly, the water runs into stove'pipe H from pipesO and U, and theninto the interior of the heater from the top, while water also runs overthe top of B and deluges the outside of the heater. At the same time Dand E are doingthe like at the bottom of the heater.

D is a half globe or reservoir of water, holding the fluid securelyuntil the heater is tipped from a perpendicular, when it dischargeswater through its pi peFinto the bottom of the heater. B and E delugethe outside, while 0 G and E F deluge the inside, of theheater.

registers, and one The reservoirs of water are three times the capacityof the warm-air chamber and heater, to insure the absoluteextinguishment of fire.

The jacket K would ordinarily be a sufficient protection, but thereservoirs of water make an absolute protection.

A similar incasement of lamps would extinguish them. No drawing of lampsis shown, but the manner is obvious, from what has been shown in theheater.

A heater, with a jacket reaching around the stove-pipe and extending apart way down from the top, leaving the rest of the heater open to view,with like reservoirs would be a good arrangement and modification ofthis device, and could be used with all kinds of heaters or stoves, butthe device shown in the reservoirs E and D beneath drawings is believedto be the only device which will insure absolute extinction of fire.

Having fully described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. The combination and arrangement of the the heater G, for the purposesspecified.

2. The combination and arrangement of reservoirs B, D, and E, with pipesO 0, whereby the inner and outer surface of the heater G is deluged atthe same time, substantially as described,
